Specification of Letters Patent.

Patented May 3, 1910.

Application filed May 27, 1909. Serial No. 498,607.

To all whom it may concern:

Be it known that I, ALBERT HENRY, a citizen of the United States,residing at Nebraska City, in the county of Otoe and State of Nebraska,have invented a new and useful Smoke-Stack, of which the, following is aspecification.

This invention is designed to provide an improved smoke stack or chimneywhich is strong and durable, and also simple and inexpensive. The stackis composed of a series of hollow tile sections surrounded by a metalliccasing containing a filler of cement.

The invention also has for its object to provide an improved jointbetween the tile sections, and to provide means for the attachment ofguys.

With the hereinstated objects in View, the invention consists in a novelconstruction and arrangement of arts to be hereinafter described andclaimed, reference being had to the drawing hereto annexed forming apart of this specification, in which drawings- Figure l is a verticalsectional view of a stack or chimney constructed in accordance with theinvention; Fig. 2 is a horizontal section on the line 2 2 of Fig. l..

As shown in the drawings, the stack or chimney comprises a series ofhollow tile sections 5, which are assembled endwise to the desiredheight. The contiguous ends of a pair of sections have flat and inclinedfaces 6 and 7 respectively, the fiat faces opening to the outer surfaceof the stack, and the inclined faces to the inner surface thereof,whereby a recess is had on one of the ends of the sections, and a beadon the contiguous end of the adjacent section, in which recess the saidbead seats. By shaping the ends of the sections as stated, a joint ishad between the same which requires no binder, as the sections are allheld in proper alinement.

Surrounding the tile structure is a metallic casing 8 which extends fromthe base to the top of the stack. This casing is spaced a short distancefrom the outer surface of the tile sections, and in said space isreceived a cement'filler 9 which will be packed tightly therein andwhich entirely surrounds the tile sections. After the cement sets, a

strong and rigid structure is had which will successfully withstand highwinds. The ends of the casing are bent over the base and the top of thestack respectively as clearly shown in Fig. l, whereby the tile sectionsare securely clamped to ether.

The stack is widenec or enlarged at its base by flaring the end of thecasing, so that the same sized tiles may be used throughout the entireheight of the stack with the exception of the first one, which,preferably has a bell mouth 10 as shown which tits over a suitable castiron cap at the end of the brick base.

At a suitable distance from the base of the stack, is a band 11, saidband being securely riveted to the easing 8. To said band are riveted orotherwise secured plates 12 having outstanding perforated ears 13 forthe attachment of guy wires or rods 14.

The advantage of the hereindescribed structure is that it is not liableto damage by varying temperatures, and it is proof against corrosionfrom creosote, sulfuric gases, etc., the sections 5 being glazed orvitrified tile, cement, clay or other suitable material. The casing 8has a coating of asphaltum to prevent rust.

The stack can be easily built, and is strong and rigid, the filler 9solidifying the whole structure. In the drawing, the stack is shown ascircular in cross section, but the shape is immaterial, and may bevaried. It is however, advisable to have the shape of the casing conformto the shape of the tile sections.

Vhat is claimed is:

A stack comprising a series of hollow tile sections assembled endwise, ametallic casino' surrounding the sections, the upper anc lower ends ofthe easing extending over the ends of the upper and lower tile sectionsfor binding said sections together, and a filler of cement between thecasing and tile sections. a

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.

ALBERT HENRY.
